People usually face the information overload by following a limited number of sources which best fit their interests. It has thus become important to address issues like who gets followed and how to allow people to discover new and better information sources. In this paper we conduct an empirical analysis of different online social networking sites and draw inspiration from its results to present different source selection strategies in an adaptive model for social recommendation. We show that local search rules which enhance the typical topological features of real social communities give rise to network configurations that are globally optimal. These rules create networks which are effective in information diffusion and resemble structures resulting from real social systems. publisher: American Physical Society date: 2012-04 type: Article type: PeerReviewed format: application/pdf language: en rights: cc_by_nc identifier: http://eprints.imtlucca.it/2843/1/1107.4491v2.pdf identifier: Cimini, Giulio and Chen, Duanbing and Medo, Matúš and Lü, Linyuan and Zhang, Yi-Cheng and Zhou, Tao Enhancing topology adaptation in information-sharing social networks.
